Replaced the cracked keypad on our RV Lock. The unit is about three years old (I think, seems I remember buying it at the Urbanna Rally in '14). Since we full-time and use the keypad to lock and unlock the trailer every day, I thought that was a pretty good service life.
Replacement keypads are available on the RV Lock site for about $10 and $2 for shipping (in an envelope via USPS). I ordered late last week and it arrived yesterday. Instructions for replacing the keypad are included in the package.
Here's the outside half of the lock ready for surgery.
Disassembly involves removing the five screws that hold on the keypad assembly from the back, pulling the rubber pad from behind the keypad and pushing the old keypad membrane off from behind (it just sticks onto the handle from the front). I removed any remaining adhesive from the old keypad, as well. The new keypad peels off the plastic backing it is shipped on and presses into place onto the handle assembly.
Here's a comparison of the new vs. old keypad. Ours was cracked on the unlock button and the 7/8 button. It looks a little rougher than it was when I started since the removal process involved pressing it out from behind which caused some additional cracks and bends.
And here it is reassembled. The whole process took about 15 minutes including removing the assembly from the door, fixing the keypad and reinstalling the assembly back on the door. (Taking pictures slowed the process slightly, as well).
